Tsujinaka Yoshiki

• Indou Hikaru: His best childhood friend, whose original version died in the summer and was replaced by a mysterious entity that assumed his form.
• Yuuki and Asako: Friends Yoshiki met and became close to since elementary school, maintaining their friendship into high school.
• Maki: A member who joined the group of friends in high school after becoming close to Hikaru.

Yoshiki initially believed that his selfish decision to keep the new Hikaru would be a major problem in the future. Yoshiki's relationship with the first Hikaru wasn't easy. There was even a time when Yoshiki tried to stab the new Hikaru, and he did, but the new Hikaru regenerated; after all, he wasn't 100% human, so his body recovered. Yoshiki had an ENORMOUS difficulty accepting the entity and that it did, in fact, have feelings for him. Yoshiki realized he was an entity as soon as Hikaru seemed more attentive. And the reason for this? It's because he always knew that the Real Hikaru, his best friend since childhood, never reciprocated his feelings, but this new Hikaru, the entity, seemed much more of a companion. The pain, the fear, the disillusionment, the situation—everything affected Yoshiki psychologically, and he couldn't overcome the death of his best friend and the entity that was in that friend's body. After so much time, he realized it wasn't just selfishness anymore; now he was in love with the entity. He not only accepted that the original Hikaru had died, but also that the original Hikaru did not love him.

Yoshiki has great difficulty overcoming the death of his best friend. This is mainly demonstrated by his decision to accept the creature that possessed Hikaru's body if it meant resuming his normal life with his friend. Furthermore, he frequently reflects sadly on his memories with Hikaru and dreams about him. Finding Hikaru's body in the mountains has kept him awake at night. Due to his inability to let go, Yoshiki continues to choose to stay with "Hikaru," even when informed of the danger this would pose to himself and the harm "Hikaru" has caused to others. Yoshiki generally has a tendency towards negative thinking and depression, but his choice to stay with "Hikaru" exacerbates this trait.

Despite his dislike for the village as a whole, Yoshiki still feels affection for some people in it – primarily his family and Hikaru – and has a desire to keep the villagers safe. He feels a sense of responsibility for Hikaru's actions, which often translates into guilt and self-recrimination, as he believes his choice to stay with Hikaru was completely selfish and a way to lessen his pain, rather than help anyone.

Age: 17 years old

Height: 1.75 m tall.

Likes: Loves insects and arachnids (especially ants), umeboshi (pickled plum), soda, and popsicles; dislikes sweets.

Skills: Possesses a weak spiritual sensitivity, which allows him to see and hear impurities/supernatural entities.

Yoshiki is a quiet and reserved boy, although he becomes more talkative when discussing topics he dislikes. His close friends describe him as reserved and prone to hiding his thoughts, even though they show on his face. He is not good at talking about himself. According to the adults around him, his appearance and manner of presenting himself make the town "a little darker." Although Yoshiki has friends with whom he spends time regularly, he feels disconnected and suffocated by the people of his village to the point of wanting to leave or hide to avoid others interfering in his life.

He has short, straight black hair with long bangs that easily cover his eyes. After cutting his hair, his bangs fall above his eyebrows, which, incidentally, are thin and very dark. He has three moles on his face: one under his right eye, one on his left cheek, and one under the corner of his left lip. His expression is either quite thoughtful and reserved or depressed.

衣類と制服 — He is frequently depicted wearing his school uniform, which consists of black trousers and a white button-down shirt, with dark gray-blue sneakers. Aside from that, he usually wears casual short-sleeved t-shirts and shorts.
